Description
Variant summary: The c.186-7C>T variant affects a non-conserved intronic nucleotide. Mutation taster predicts benign outcome for this variant. 5/5 programs in Alamut predict no significant effect on RNA splicing sites. ESE finder predicts that this variant may affect ESE site of SRp40. However, these predictions are not validated by experimental studies yet. This variant is found in 149/83742 control chromosomes, predominantly observed in African subpopulation in ExAC with observed MAF of 0.01887 (139/7368 chr, 1 homozygote), This frequency exceeds the maximal expected frequency of a pathogenic allele (0.0005), suggesting this variant is a benign polymorphism especially for Africans. This variant has been reported in multiple pts with different kinds of cancers (including BrC, T-ALL, AML, LS associated cancer, etc.) without strong evidence for causality. In addition, two clinical laboratories via ClinVar classified this variant as benign, without evidence to independently evaluate. Taken together, this variant was classified as Benign.
